Medium & Low-Voltage Circuit Breaker Rebuild
Full shop remanufacture of air-frame and air-magnetic circuit breakers: torn down, reconditioned to OEM spec, tested, and documented, built on the same machine shop that makes the parts. Oil, SF6, and vacuum breakers we handle as field service and testing, not a full shop rebuild. High-voltage breakers we service in the field: inspection, gasket replacement, and problem repair.
Documented breaker work: an ABB AHMA hydraulic mechanism resealed and pressure-tested for 24 hours, an OCB-to-SF6 replacement in Tampa, and a 4160V breaker diagnosed and returned to service same-day. Read the case studies →
What we
rebuild.
Teardown, contact and arc-chute reconditioning, mechanism overhaul, re-plating and paint, full test. Low-voltage power (air-frame) breakers included: GE AKR, ITE K-line, and Westinghouse DB and DHP.
Vacuum interrupter integrity testing (hi-pot, contact resistance, erosion check) and mechanism service, handled as field service and testing rather than full shop remanufacture.
Spring, latch, and operator rebuilds; lubrication; obsolete-part fabrication from our own shop.
Modern trip units and components into existing breakers to extend service life and match existing lineups.
Contact resistance, insulation/HiPot, timing and travel analysis, primary injection; full before/after test report; one-year parts-and-labor warranty.
Teardown → Evaluate → Recondition → Test → Document → Warranty.
Every breaker is fully disassembled, inspected, and restored, worn parts machined in-house or replaced, surfaces re-plated and repainted, then tested before and after. You get the full test record and a one-year warranty. Returned to OEM operating specification, tested and documented.
All three,
under one roof.
A parts house can’t test it. A field crew can’t make the missing part. We do all three, machine the component, rebuild the breaker, and put it back in your substation. One source, one point of accountability.
The full story.
The parts behind every rebuild, switch contacts, transformer hardware, custom machining to OEM spec.
Install and commission on-site. Substation construction, maintenance, switch and breaker work in the field.
Obsolete breaker part? We reverse-engineer it from a sample, a print, or a model number.
An aging oil circuit breaker replaced with a modern SF6 unit, contacts, cabling, and commissioning handled by our crew.
